NEWTOWN SQUARE, Pa. — Justin Rose did his part on another day of low scoring Saturday in the third round of the BMW Championship, running off four straight birdies early for a six-under 64 and a one-shot lead over Rory McIlroy and Xander Schauffele.
At stake for Rose, who is at 17 under over all, is moving to No. 1 in the world for the first time in his career.
Still ahead is a final round at soggy Aronimink Golf Club that could take more than one day to complete because of rain in the forecast, and will begin with 13 players within five shots of the lead.
